Why is Caesar considered a round character in The Tragedy of Julius Caesar?

He is considered a round character as opposed to a flat character because he is portrayed to have more depth than a character that might show up in one scene. This requires giving us time and information to know him. Think of a round character as you or a member of your family and a flat character as somebody you just met at the grocery store. Yes, their might be more to the person at the grocery store but you only are seeing so little that you only know them as another person. So, the correct answer is - Caesar is multifaceted: he is stubborn and proud, and the plebeians adore him, while the senators hate him. His story line is essential to the plot.
